Application rues September 5, 191?.

To all whom it may concern:

Be it known that l, thorn-inn llI1IWSAM,CllJlzenot the United States,residing at Peoria Heights, in the county of Peoria and State ofIllinois, have invented certain new and useful Improvements inVVindow-Latclies, and do hereby declare-that the following is a full,clear, and exact description of the invention, which will enable othersinn drawing, wherein,

skilled in the art to which it appertains to make and use the same,

This invention relates to a window latch.

It )ertains more iarticularlv to a latch used as a support for windowsashes generally, being especially adapted for sashes of railwaycoaches.

One of the objects of the invention is to provide a latch operated bygravity loc-ated in a window casing adjacent the runway of the sash. soarranged that when the sash-has been raised above the position or" thelatch,

said latch will automatically and positively fall into position bygravity where it will receive upon the said sash, and which can beraised and moved out of "2163 path of the sash all without complicationoi any kind.

Another object is to provide an exceedingly simple form of latch whoseparts cannot be broken nor get out of order, and that can be made at lowcost. i

To the end that the invention may be understood, l have lpi'o -xidedtheaccompany- Figure 1 represents an elevation of a part of a sashandits window casing in vertical section and my invention appliedthereto, one of the parts being in position to support the sash.

Fig. 2 is a similar view with the described part raised out of use. iFig. 3 shows, in perspective, a slotted plate e cutcheon. p l v 4. shoxvs, in perspective, a latch; and, Fig. 5 is a horizontal section ot' awindow casing and sash showing my invention ap plied thereto, part beingshown in section,

Sash locks as ordinarily furnished for coach windows are easily damagedand easily rendered useless because of their flimsy construction,besides offering endless opportunities for injury to the fingers. Suchlocks when damaged prevent the sash being moved at all, requiring that anew lock be installed wh1ch means a constant expense.

My device to be described, however, is

exceedingly strong, easy to operate, entirely efl'ective, and onceinstalled is a permanent,

, quired.

1 indi:-ates a part of a window casing, 2 the sash, and 3 the usualstops between which the sash 2 slides. 4: indicates a recess formed inthe casing 1 opposite the edge oi the sash.

5 is an escutcheon-plate mortised into the casing 1 so that its frontsurface will lie flush with the bottom of the slide in which the edge ofthe sash 2 is carried.

This plate is provided with a vertical slot 6, the metal beingpreferably cutaway around said slot to provide a beveled surface 7.Also, by preference, opposite edges oil the plate are provided at therear with a flanggjc 8 creating a recess atthe rear side of the plate,the recess 4 in the casing 1 correspond- .ing in width thereto, asclearly shown in opposite the described slot 6 and if theplate 5 is astamping, the tongue may be that part of the plate that is cut out totorm the slot and at its lower end preferably terminates at the bottomof the slot substantially as shown in Fig. As shown in Fig. 3, however,the tongue may be secured to the back of the plate.

In the several figures, especially in F g. l, is shown what I shall terma latch. It is preferably of a single part made up of a portion 10 inthe form of a plate from one end of which extends. substantially atright angles, a neck-portion 11 with a head 12. Preferably the underside of the neck is rounded asat 13 to lend strength thereto. The saidneck 11 and the head 12 are of a width hat will readily pass through theslot 6 of the plate The portion 10, however. is much wider so as not topass through the slot. being substantially equal, in width to the ninthof the recess and the space or recess between the flanges 8. This ismost In Fig. 1 the latch in its lowermost position for supporting thesash It rests in the bottom of the slot 6, the portion 10 bears ingagainst the inner or. rear side of the plate 5 while the head 12 restsagainst the outer surface of the plate, projecting intoth'e path of thesash. This constitutes an absolutely firm support for the sash,therebeing no possible chance of the sash falling.

The sash in order to be lowered must first be raised until. its loweredge is at or above the upper end of the slot 6 whereupon the operatormay raise the latch with the finger until said latch takes thepositionshown in Fig. 2 at the top of the slot. the head '12 having been movedupward and backward until it is moved entirely out of the path ofmovement ofthe sash.

In pushing the finger up to lift the latch it will naturally encounterthe lower end or point of the head 12 and as the head moves upward inand inward through the slot. the portion 10 will fall forward and followup upon the inner side of the plate 5, or the heel- 10 of the latch mayfollow up the tongue, the upward movement being arrested as the headstrikes and reaches the upper end of the slot. Said head will now lieoutside of the path of the sash and the latter can be lowered past itwithout difliculty, said latch being maintained in the position in whichit is placed by resting against the edge of said sash. The latter can bereadily raised and lowered without interference.

When the sash is raised to a position to release the latch thelatter'will at once drop down by gravity to its position in the path ofthe sash. being guided thereto by the tongue 9. The rear wall of therecess t may be formed to correspond to the slant ofthetongue 9 to actin the same capacity as the latter. It is preferred to use the tongue,however, since it provides a smooth working surface for the latch andwill always have the proper position with relation to the plate 5 andfor that reason the attachment can be readily and quickly set into arecess which has not been required to be exactly formed.

Several of the described devices may be placed in position in the runwayof the sash at various heights so that said sash may be held at anydesired place. The metal is beveled around the slot 6 in order that thefinger will not be injured by chance raw edges of metal. at the slot 6when pushing the latch up.

My device because of its form can be placed in the runway of the sashand, therefore, is not visible except beneath the sash when the latteris raised, being only partially visible when the sash rests upon thelatch. When the sash is closed nothing whatever projects from or marsthe appearance of the casing or the sash.

neonate My device is distinguished from others of its class in being ofa simple construction that ca'nnot be disarranged in use and that doesnot require a special knowledge of its manner of manipulation. In theuse of one of the devices of said class each person must inform himselfby actual trial the manner of operating the latch because of itspeculiar form whereas in. my device the mere lifting of the latch causesit disposal with? in the casing out of the line of movement of the sash.

Having thus described myinvention, I.

claim 1. A device for supporting a window sash comprising incombination, a plate having a vertically disposed. slot, a partextending from substantially the bottom of the slot upwardly at an angleaway from the plane of said plate and a latch including in itsconstruction a tongue adapted in one of its positions to lie in andextend. through said slot and having a portion of a width greater thanthat of the slot to lie against the inner side of said plate, said latchhaving an angled recess at its forward part creating a ledge to lieoutside said slot upon which to support the sash. 1

2. In a device for supporting a window sash, in combination, a platelocated in the bottom of the runway of the window frame having avertically arranged slot, 3 part upwardly and rearwardly inclined fromsubstantially the bottom of the said slot, and a latch comprising aportion greater in width than the slot arranged in one of its positionsto lie against the plate at that side adjacent the said inclined part,and including a ledge spaced from said portion to eXtend outwardlythrough the slot in the sash supporting position for receiving the sashupon it. r

3. In a devicefor supporting a window sash, in combination, a platelocated in the bottom of the runway of the window frame having avertically rranged slot extending therethrough, a part inclined upwardlyand inwardly from substantially the bottom of said slot, and a latchslidable within and through the slot adapted in one of its positions tolie wholly inward from the outer face of the plate and in another of itspositions to extend partially through the said slot outside the plate inthe path of the sash the part thereof extending through the slotincluding an abrupt ledge to-rreceive the sash upon it. a y a V Intestimony whereof I affix my signature in presence of two witnesses.
